Chinese Green Tech Exports: Solar Inverters and Heat Pumps Flooding European Markets

Solar inverter market dominance#

Huawei and Sungrow together control approximately 55% of the global solar inverter market, with European market share exceeding 60% for residential and commercial segments. Chinese inverters are priced 30-40% below European alternatives from SMA and Fronius while offering comparable or superior technical specifications including higher conversion efficiency and integrated monitoring capabilities. The rapid buildout of solar capacity across Europe under REPowerEU targets has created demand volumes that only Chinese manufacturers can fulfil at the required pace. European installers have largely defaulted to Chinese inverters despite periodic concerns about data security and supply chain concentration.

Heat pump export surge#

Chinese heat pump manufacturers including Midea, Gree, and Hisense exported over 2.5 million units to Europe in 2025, capturing roughly 45% of the market by volume. The price gap is substantial: a Chinese air-source heat pump system costs EUR 3,000-5,000 installed compared to EUR 7,000-12,000 for European brands like Vaillant or Daikin. EU gas boiler phase-out timelines have created urgent demand that domestic manufacturers cannot meet, effectively requiring Chinese imports to achieve climate targets. Quality improvements in Chinese heat pumps have been rapid, with leading models now achieving comparable COP ratings and noise levels to European premium brands.

EU anti-subsidy investigations#

The European Commission launched anti-subsidy investigations into Chinese solar inverter imports in late 2025, following the precedent set by EV and solar panel investigations. Heat pump imports face similar scrutiny, with European industry associations arguing that state subsidies give Chinese manufacturers unfair competitive advantages. The investigations could result in countervailing duties of 15-35%, though the EU faces a difficult balancing act between protecting domestic industry and meeting its own climate deployment targets. Importers should prepare for potential duty retroactivity and consider diversifying supplier bases to mitigate tariff risk.

Supply chain security concerns#

European energy security strategies increasingly recognise the risk of depending on Chinese manufacturers for critical clean energy infrastructure components. Solar inverters connect to grid management systems and could theoretically be used for remote grid manipulation, a concern that has led several EU member states to restrict Huawei inverters from critical infrastructure applications. Heat pump dependency is less acute from a security perspective but raises industrial policy concerns about the hollowing out of European manufacturing capabilities. The tension between climate urgency and industrial sovereignty will define European clean tech trade policy for the coming decade.

Localisation strategies by Chinese manufacturers#

Sungrow has established European assembly operations in Germany, while Midea is expanding its Italian heat pump factory to serve EU markets with locally manufactured products. These moves mirror the broader pattern of Chinese manufacturers establishing EU production to navigate potential trade barriers while maintaining cost advantages through Chinese-sourced components. The effectiveness of these localisation strategies depends on how EU rules of origin are applied to partially assembled products.
